Study of Array Detector Based Spectrophotometer for Sphere Photometry

Photometry is an important area of metrology which deals with the measurement of light as seen by the human eye. In order to study the spectrum of wide range light sources, spectrophotometer plays an important role in photometry. In setting up of spectrophotometer based integrating sphere system, the characterization of the spectrophotometer plays an important role. In the present work, the study of the effect of variation of integration time on the output signal of the spectrophotometer is performed. As expected, the signal at different wavelengths linearly varies with integration time.
